I-Ultrasonic isiphenduke indawo yokucwaninga emhlabeni wonke ngenxa yokukhiqizwa kwayo ekudluliseni okukhulu, ukudluliswa kokushisa kanye nokusabela kwamakhemikhali.Ngokuthuthuka nokuthandwa kwemishini yamandla e-ultrasonic, enye inqubekelaphambili yenziwe ekuthuthukisweni kwezimboni eYurophu naseMelika.Ukuthuthukiswa kwesayensi nobuchwepheshe eShayina sekuphenduke imikhakha emisha ehlukahlukene - i-sonochemistry.Ukuthuthuka kwayo kuthonywe umsebenzi omningi owenziwe ngethiyori nasekusetshenzisweni kwayo.

Igagasi elibizwa ngokuthi i-ultrasonic wave ngokuvamile libhekisela kumagagasi e-acoustic anebanga lemvamisa elingu-20k-10mhz.Amandla ayo okusebenza emkhakheni wamakhemikhali ikakhulukazi avela ku-ultrasonic cavitation.Nge-shock wave enamandla kanye ne-microjet enesivinini esingaphezu kuka-100m/s, i-high gradient shear ye-shock wave kanye ne-microjet ingakhiqiza ama-hydroxyl radicals kwisisombululo esinamanzi.Imiphumela ehambisanayo yomzimba namakhemikhali ikakhulukazi imiphumela yemishini (ukushaqeka kwe-acoustic, i-shock wave, i-microjet, njll.), imiphumela yokushisa (izinga lokushisa eliphezulu lendawo kanye nokucindezela okukhulu, ukukhuphuka kwezinga lokushisa lilonke), imiphumela yokubona (sonoluminescence) kanye nemiphumela yokuvula (ama-hydroxyl radicals akhona. ekhiqizwe ngesisombululo esinamanzi).Imiphumela emine ayihlukanisiwe, Kunalokho, isebenzisana futhi ikhuthazane ukusheshisa inqubo yokusabela.

Njengamanje, ucwaningo lokusetshenziswa kwe-ultrasound luye lwafakazela ukuthi i-ultrasound ingavula amaseli ezinto eziphilayo futhi ikhuthaze umzimba.I-Low intensity ultrasound ngeke ilimaze ukwakheka okuphelele kweseli, kodwa ingathuthukisa umsebenzi we-metabolic weseli, yandise ukungeneka nokukhetha kwe-membrane yeseli, futhi ikhuthaze umsebenzi we-biological catalytic we-enzyme.I-high-intensity ultrasonic wave ingasusa i-enzyme, yenze i-colloid esitokisini iqhume futhi i-sedimentation ngemva kwe-oscillation eqinile, futhi i-liquefy noma i-emulsify ijeli, ngaleyo ndlela yenza amabhaktheriya alahlekelwe umsebenzi wezinto eziphilayo.Ngaphezu kwalokho.Izinga lokushisa elisheshayo, ukuguquka kwezinga lokushisa, ukucindezela okuphezulu okusheshayo kanye noshintsho lwengcindezi olubangelwa i-ultrasonic cavitation izobulala amanye amabhaktheriya oketshezini, ivule igciwane, futhi ibhubhise nodonga lwamaseli wezinye izinto ezincane ze-emblem.I-higher intensity ultrasound ingabhubhisa udonga lwamaseli futhi ikhulule izinto ezisengqamuzaneni.Le miphumela yezinto eziphilayo iyasebenza nakumphumela we-ultrasound kulokho okuhlosiwe.Ngenxa yobukhethekile besakhiwo se-algal cell.Kukhona futhi indlela ekhethekile yokucindezelwa nokususwa kwe-algae ye-ultrasonic, okungukuthi, isikhwama somoya esitokisini se-algal sisetshenziswa njenge-nucleus ye-cavitation ye-bubble cavitation, futhi isikhwama somoya siphukile lapho i-bubble cavitation iphukile, okuholela ekutheni i-algal cell ilahlekelwa amandla okulawula ukuntanta.
